AV Switch Self-Diagnosis FunctionEKS007KI
It can check ON/OFF operation of each switch in the AV switch and diagnose the input signals from the steer-
ing switch.
STARTING THE SELF-DIAGNOSIS MODE
1. Turn ignition switch from OFF to ACC.
2. Within 10 seconds press and hold the switches “PAUSE/MUTE”
and “PREV” simultaneously for 3 seconds.
Then the self-diagnosis operates. A single beep indicates self-
diagnosis mode is active.
3. Press each switch and listen for beep.
NOTE:
CD player LOAD and EJECT buttons are not included in this test
and will not beep when pressed.
EXITING THE SELF-DIAGNOSIS MODE

Turn ignition switch OFF. Then the self-diagnosis ends.
DIAGNOSIS FUNCTION

It can check for continuity of the switches by sounding the beep when each AV switch and steering switch
is pressed.

It can check for continuity of harness between AV switch and steering switch.

NAVIGATION SYSTEMPFP:25915
System DescriptionEKS007LI
The navigation system periodically calculates the vehicle's current
position according to the following three signals: Travel distance of
the vehicle as determined by the vehicle speed sensor, turning angle
of the vehicle as determined by the gyroscope (angular velocity sen-
sor), and the direction of vehicle travel as determined by the GPS
antenna (GPS information).
The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data read from the map DVD-
ROM, which is stored in the DVD-ROM drive (map-matching), and
indicated on the screen with a current-location mark.
By comparing the vehicle position detection results found by the
GPS and by map-matching, more accurate vehicle position data can
be used.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.
TRAVEL DISTANCE
Travel distance calculations are based on the vehicle speed sensor input signal. Therefore, the calculation
may become incorrect as the tires wear down. To prevent this, an automatic distance fine adjustment function
has been adopted. Adjustments can be made in extreme cases (such as driving with tire chain fitted on tires).
Refer to AV-107, "
Confirmation/Adjustment Mode" .
TRAVEL DIRECTION
Change in the travel direction of the vehicle is calculated by a gyroscope (angular velocity sensor) and a GPS
antenna (GPS information). As the gyroscope and GPS antenna have both merit and demerit, input signals
from them are prioritized in each situation. However, this order of priority may change in accordance with more
detailed travel conditions so that the travel direction is detected more accurately.
MAP-MATCHING
Map-matching is a function that repositions the vehicle on the road
map when a new location is judged to be the most accurate. This is
done by comparing the current vehicle position, calculated by the
method described in the position detection principle, with the road
map data around the vehicle, read from the map DVD-ROM stored in
the DVD-ROM drive.
Therefore, the vehicle position may not be corrected after the vehicle
is driven over a certain distance or time in which GPS information is
hard to receive. In this case, the current-location mark on the display
must be corrected manually.
CAUTION:
The road map data is based on data stored in the map DVD-
ROM.

Gyroscope (angular velocity sensor)

Can detect the vehicle's turning angle
quite accurately.
Direction errors may accumulate when the
vehicle is driven for long distances without
stopping.
GPS antenna (GPS information)

Can detect the vehicle's travel direction
(North/South/East/West).
Correct direction cannot be detected when
the vehicle speed is low.
